You shouldn't place MuseHub and Musecy SM Ltd automatically in the startup menu to allow in the background.
I am trying to be positive about Musescore 4. Though, I am going to wait a few months before transferring over.
But placing things in the background can cause many unnecessary problems.
For example, I am taking a Pennsylvania notary test on December 29th, and Musehub actually interfered with making my computer compatible for the online test. I just spent 30 minutes trying to figure out how to remove Musehub from my Applications folder.
I would always to prefer to manually update anything (or even be forced to manually update) rather than have a program do it for me.
Anyway, best of luck. The interface looks beautiful, the note engraving is noticeably improved and the 'computer' sounds are wonderful. Best of luck.
